Stihl MSA 200 C-BQ Instruction Manual - Page 8

English Properly secure your chain saw to prevent turnover and damage to the chain saw. Before Operation Take off the chain guard (scabbard) and inspect the chain saw for proper condition and operation. (See the maintenance chart near the end of the instruction manual.) WARNING Always check your chain saw for proper condition and operation before starting, particularly the trigger switch, trigger switch lockout, front handle guard and cutting attachment. The trigger switch and the trigger switch lockout must move freely and always spring back to the stop position. Ensure that the trigger switch will not engage when the trigger switch lockout is not pressed. Never attempt to modify the controls or safety devices. To reduce the risk of injury, never use a saw if any part is damaged or does not function properly. Take the saw to your local STIHL servicing dealer. Do not use the saw until the problem has been rectified. For proper assembly of the bar and chain follow the procedure described in the chapter "Mounting the Bar and Chain" of your instruction manual. STIHL Oilomatic saw chain, guide bar and sprocket must match each other in gauge and pitch. Before replacing any bar and chain, see the chapter entitled "Specifications" in the instruction manual and the chapter "Reactive Forces including Kickback." Since longer bars add weight and may be more difficult to control, select the shortest bar that will meet your cutting needs. WARNING Proper tension of the saw chain is extremely important. In order to avoid improper setting, the tensioning procedure must be followed as described in your manual. Always make sure the hexagonal nut(s) for the sprocket cover is (are) tightened securely after tensioning the saw chain in order to secure the bar. Never start the chain saw with the sprocket cover loose. Check saw chain tension once more after having tightened the nut(s) and thereafter at regular intervals (whenever the saw is shut off). If the saw chain becomes loose while cutting, switch off the motor and engage the chain brake by moving the front hand guard to ƒ, remove the battery from the chain saw and then tighten. Never try to adjust the saw chain while the motor is running! WARNING After adjusting a saw chain, let the motor run for a while, then switch motor off and engage the chain brake by moving the front hand guard to ƒ. Remove the battery from the chain saw and recheck saw chain tension. Proper saw chain tension is very important at all times. Keep the handles clean and dry at all times; it is particularly important to keep them free of moisture, pitch, oil, grease or resin in order for you to maintain a firm grip and properly control your chain saw. Check contacts in battery compartment for foreign matter. Keep clean. Fit the battery correctly - it must engage audibly. WARNING Before disengaging the chain brake and switching on your chain saw, be sure that the guide bar and saw chain are clear of you and all other obstructions and objects, including the ground. If the upper quadrant of the tip of the bar touches any object, it may cause kickback to occur (see section on reactive forces). Never attempt to start the chain saw when the guide bar is in a cut or kerf. For specific starting instructions, see the chapter "Switching On" of your instruction manual. Battery WARNING Risk of fire, explosion and/or burns, including chemical burns. Do not disassemble, crush, heat above 212 °F (100 °C), expose to fire or incinerate. Never expose the battery to microwaves or high pressures. Do not place the battery on or near fires, stoves or in other high-temperature locations. Do not place the battery in direct sunlight or store it inside a vehicle in hot weather. Doing so may cause the battery to generate heat, rupture or 6 MSA 160 C, MSA 200 C
